Software Engineer Intern (Summer 2027 - Chicago)

As a Software Engineer Intern, you’ll work side-by-side with your mentor and teammates to build real-world applications that power a global trading firm.

Your projects will be scoped based on your team’s real needs — not hypothetical tasks — and your mentor will be fully invested in helping you build high-quality software that’s designed to last.

You’ll contribute to meaningful projects solving trading problems and improving the performance, reliability, and scalability of our systems — and you’ll see your code hit production in real time.

Optiver is building with cutting edge AI technology in the most competitive, data rich landscapes in the world: financial markets.

That means no two days are the same, and every day brings new, exciting technical challenges to solve.
